Well, actually, your version of Rivanone is now the version of her I have in my head now.

Aaaah, good question.Well, she mainly plays the harp - and it is the one she gave to Sigrid and which is now in the Temple of the Two in the Imperial city. But it is not her favourite instrument. She loves wind instruments a lot (flutes and the like) but as she can’t play then and sing at the same time, she prefers playing strings instruments - and the more exotic they are, the better. There is a room in the Trencavel manor devoted to all the instruments she has collected from all over the world (and young Lucien and J'Ghasta are strictly prohibited to set a foot there under threat of immediate and very painful death )

So, to finally answer your question, she is mainly seen playing the harp as well as the zither ( [link] ) and the gusle ([link] ).But her true love is this one : [link] , the Saung, a rare kind of Akaviri harp (she has one shaped as a crocodile 8D ). She rarely plays it in public though as it sounds very strange and is not very popular among people who listen to her music…
